This is the old 1/144 Hammer Hammer kit. Since it's a simple kit, I've packed it with various ideas!
Specifically, I've added ball joints to various parts to make it easier to pose.
I'll explain the modifications in detail.
I used many Ball Joint Arms to install ball joints in the neck, shoulder thrusters, skirt, and hip joints.
I used joint blocks to increase the width of the shoulders and expand the range of motion.
